Fifteen years ago, not all businesses could accept credit cards. Square set out to change that – inventing the first mobile card reader of its kind. Square then moved far beyond its origins as a payment processor to building new tools and solutions for the future. Today, Square is the largest business technology platform serving all kinds of businesses. The Square operating system allows business owners to sell anywhere, work more efficiently, manage inventory, communicate with customers, book appointments, course meals, order online, and much more.
